On Tuesday at approximately 7:40 am local time, three people were killed when an Amtrak Cascades train traveling for the first time on a new route between Seattle and Portland, Oregon in the US derailed south of DuPont, Washington while crossing a bridge over the I-5 freeway, with parts of the train falling onto the highway. One train car dangled from the bridge, and some lay in an area of woodland on the other side from the highway. Diesel fuel leaked from one car.

77 passengers and seven crew members, plus a technician, were on board the twelve-car train at the time of the derailment. Seven vehicles were hit by the falling train, including two trucks. According to the police, approximately one hundred people were sent to hospitals in Tacoma, Lakewood, Gig Harbor, Olympia and on the military Joint Base Lewis–McChord, ten with serious injuries. The deaths and serious injuries were all from the train. 19 train passengers were not injured and were transported by bus to the city hall in DuPont.

The train was the inaugural run of Train 501 on a new inland route, the Point Defiance Bypass, using track rebuilt at a cost of US$181 million that had previously been used exclusively by freight and military trains. It left Seattle at 6:00 am local time and had just left a new Amtrak station in Tacoma when it derailed when taking a curve onto the bridge. It had two locomotives attached, one each at the front and the rear. According to Bella Dinh-Zarr, a spokesperson for the National Transportation Safety Board, the data recorder from the rear locomotive, the only section of the train that did not derail indicated the train had been traveling at about 80 mph (130 kph) when the speed limit on the curved section of track was 30 mph. Data from the Amtrak train tracker app posted at transitdocs.com also indicated the train’s speed was 81 mph shortly before it derailed. Statements to the Seattle Times from SoundTransit, the regional agency that owns and maintains the rail line, and Barbara LaBoe, a spokesperson for the Washington State Department of Transportation, said most of the track had a speed limit of 79 mph but that the lower speed limit at the accident location was marked by signs two miles ahead. A federal official was quoted on Wednesday as telling the Associated Press that one suggestion was that the train engineer lost “situational awareness” due to being distracted in the cab.

Passengers reported having had to punch or kick out windows to leave the train because the emergency doors did not work, and seeing people lying on the ground as if they had been thrown out, one pinned under the wreckage. One passenger, Chris Karnes, described the sound of the derailment as “like being on the inside of an aluminum can being crushed”. A conductor on the train stated in his emergency call, “We were coming around the corner to take the bridge over I-5 there … and we went on the ground.”

Positive train control, an automated system for warning and slowing trains that are proceeding too fast, might have prevented the accident. According to Richard Anderson, president of Amtrak, it was installed on this section of track but had yet to be activated.
